plinth material

The New Linn Plinth is a Resin Impregnated Densified Wood Board, which is most likely CNC Machined to produce the Peripheral Form to support other structures.

The method, if done as above leaves quite a large cut out as a wastage, this wastage would have been much better used to produce an update of the Sub Chassis. Two Parts of this material used in conjunction will have had a much improved impact than remaining with a Aluminium Material.

Linn's selected board materials has a low number of Plies per 25mm, it looks like they missed this importance, they material is cross grain. 

I have costed the Raw Material for the Bedroc using the cost I know for other produced materials of the similar design, but with more Tiers per 25mm, resulting in increased costs.

The Bedroc as a Blank Material in a Plinth Dimension is approx' £350 per Blank if a full Board is purchased and reduced to Blank Dimensions.

Bring on the DIYer and Copyists out for a quick buck   

I'd have a look at the new Linn plinth. I have heard from a friend that is sounds great... maybe not enough for me to justify buying. Might help with material and construction. 

10 mm seems way too thin just from a support perspective to be the only layer of the plinth. If it were a sub-layer what might you consider for the top layer?  I have a left over slate piece that's about 18mm thick.  My current table has a 3rd bottom "skirt" layer just to obscure the view of the motor. 

When I was building the current table I saw folks suggesting bamboo cutting boards from IKEA.

= for Bamboo, did a 301 in it a few years back, excelent if not a pain to work with. 

Typically in Panzerholz the B25 Type Material is used which is a 25mm Thick Board with 25 Plies per 25mm.

More recently I have seen lesser Thicknesses used and only once seen a Thicker than 25mm used which was at 32mm.

The individual in the UK who was instrumental in bringing  P'holz and Permali to the forefront as a Structure Material, made it known 10mm was the thickness that was generating the ideal damping / dissipation measurements. It was made known additional Thickness was not going to improve things. That is not to say an additional thickness is without attributes, the sonic is known to be effected using different thicknesses. I have a Permali Board at 75mm Thick, to one day become a Plinth Material, but not a conventional design.

From my end, if a Thick Plinth is required for aesthetic purposes, there is the option to add a Perimeter Skirt to the desired dimension.

A few years past I was to have a few experiences of a Garrard 401 mounted on a   Highly Compressed Bamboo Board, that I know as a material, is not too different from Densified Wood measurements. The Demo' of the 401 from the recollections of past experiences at the time, was from my assessment the best I had heard from a 401.

The Bamboo Board material is one that can be looked at as well, especially for Idler Drives, this is also to be seen on LH as a Plinth Material. 

Note: There is something quite special to be experienced when using a Sub Plinth made from a Resin Impregnated Densified Wood Board in conjunction with TT's Plinth. Separation Footers will also add to the fine tuning the sonic, there are plenty of trials to be had with footer used under a Sub Plinth and used as a Plinth Separator.

Thanks pindac.  I haven't yet ventured to Lenco Heaven but spent many hours there when I built one out of slate several years ago. At that time I only saw a few mentions of the material but not any projects with it.  Do you suggest 2-3, 25mm layers over one 70mm slab?

I strongly recommend the use of a Resin Impregnated Densified Wood Board, to be used a Plinth Material.

Looking into the Lenco Projects documented on Lenco Heaven will show builds using this Material Type.

The most important to have knowledge, when purchasing this type of Board Material, is that the Structure for the Board is best when the Plies are Cross Grain Orientation and the more Laminations per 25mm thickness is the most desirable. 

There are plenty of Phenolic Boards, but the critical Phenolic Board for this purpose, is the board produced to be impregnated, where this is carried out in a Vacuum Chamber under high pressure, with the Chamber at a High Temperature.

This Board Type does take a finish and can be left natural colour with a patina through to a gloss finish, there are very nice Aesthetics for Plinths produced from this Board Type to be seen with a Veneer Covering as well.
